INSIDE KOREA'S DMZ: The most DANGEROUS place on earth

Heavily armed North and South Korean forces are aligned against each other. There's little movement along the demilitarised military zone -- DMZ -- that separates North and South Korea.

Barbed wires, watchtowers and landmines dot the DMZ -- it is the most heavily-fortified border in the world! The North and South Korean troops stand prepared for a battle anytime.

The two sides have remained in a formal state of war since an armistice ended combat in the Korean War in 1953. The DMZ was established then and there has never been a peace treaty.

We take a look at life on the DMZ where there's no sign of tension easing, where the Cold War still persists.
